"We are living through the biggest disaster in Bahia's history," said Bahia Governor Rui Costa, who has been overseeing rescue operations in the afflicted areas since Saturday.

"The water is starting to decline at the source of the Cachoeira River and it is expected to improve in the days to come, although slowly," Costa said.

Houses were under water and streets turned into rivers in several municipalities in the south of the state, pounded since Thursday by heavy rainfall that caused dams to burst and rivers to overflow at the weekend.

In Itapetinga, AFP aerial footage showed three men paddling on a straw mattress in a street surrounded by houses with water reaching their windows.

Another 358 people have been injured since the onset of the heavy rains in November. In total, authorities estimate that 116 municipalities, including at least 100 that are in a state of emergency, have been affected by the heavy rains.
